3' Claims. 1

"This invention comprises novel and useful improvements in trafficcontrol lights, and more particularly pertains to a traffic controllight of the type havingan indicatormoveably mounted thereon to indicatethe time-remaining during which a certain light will-be actuated.

'An important object of this invention is to provide-a tralficcontrol'light'having a pair of relativelytransverse' light units, eachof which units have an indicator moveably mounted thereon to indicatethe-time remaining during which Go light, in each unit, will beactuated, which 7 indicator is moved only when the "Go light withwhich'it 'isassociated is energized, to thereby preclude drivers whoare'waiting out a Stop signal, from knowing prior to the time the Stopsignal changes to Go, just when the signal will change, whichdevice'nevertheless informs the motorists, who can see" the Go'signal ofthe other traffic light unit, of the time remaining during which the *Gosignal will be illuminated.

Another important object of this invention is to'provide a trafficcontrol light, in accordance with the foregoing object, in which theindicators may be 'driven by acommon motor in a complete path about theGo light, with which-they are associated, at relatively different ratesf speeds, so that the duration of actuationof'the Go lights of therelatively transverse light units, may be relatively different.

Yet another object cf this invention is to provide a traffic controllight, in accordance with the'foregoing objects in whichthemotor-vrh-ich drives theindicators, times the'actuation of the lights"in bothof the units, and also times the actuation of the mechanism forselectively drivingly connecting each of the indicators'to the motor,whereby variations in thespeed of the motor will not adverselyelfect therelative timing of the lights and indicators.

An important feature of'this invention-resides in the provision of apair of relatively transverse light units, each having an indicatormounted for movement around one of the lights thereof to indicate thetime remaining during which that light will be actuated, with a commonmotor for driving both ofithe indicatoraand means for simultaneously,alternately drivingly engaging one of the indicators with the motorwhile disengaging the other of the indicators from the motor, to therebypermit the indicators to be driven at relatively different rates througha given path of movement, by a single motor.

Yet another feature of this invention resides in the provision of thetraffic control light, in

accordance with the foregoing feature, with a mechanism controlled bythe motor-for actuating the means for engaging anddisengaging; theindicatorsfrom the' motor, whereby variations in the speed of the motorwill not affect the relative timing of the movement of the indicatorand-the time at which the indicator will be operatively disconnectedfrom the motor.

Still another feature-of this invention resides in theprovision of atrafiiccontrol'light, in accordance with the foregoing features, in"which the motor also controls the energization ofpthe other lights ineach unit, whereby variations in the speed of the motor will not affectthe timing of the energization of the; lights and the movement of theindicators.

A further feature of this invention resides in the provision of "atrafiic'control light, including a housing with relativelyperpendicularlights thereon, and indicators each mounted in the houseing for-rotation about ahorizontallyjdisposed indicator support shaft;together withga motor'having a vertically disposed drive shaft, andclutch means carried by the support shaftsgforselectively drivinglyengaging the support shafts and the drive shafts, with a clutch actuatorengag-,

ing each of theclutch-means to move one, into its engaging positionwhile moving the other into its inoperative position.

"These, together-With variousancillary objects and features are-attainedby this device,1the .preferred embodiment of which has been illustratedinthe accompanying drawings wherein;

Reference is now made more specifically to the accompanying drawingswherein there is illustrated a trafiic signal light, indicated generallyby the numeral I which includes a housing I2, indicator light assemblysI4, a clutch mechanism I6 for operatviely connecting the indicatorlights to a motor drive shaft, and a timer assembly I8.

The housing I2 includes a bottom wall which may be mounted upon asupporting post 22, as by the mounting flange 24, and upstanding sidewalls 26, 28, and 32 are secured to the bottom wall as by the angleirons 34 and fasteners 36,

best shown in Figure 4. A cap member 38 is' secured to the upper ends ofthe side walls, as by fasteners 40.

Each of the side Walls 26 and 28 are provided with vertically spacedapertures or openings, an upper lamp housing 42 which is disposed in oneof the openings and secured thereto as by the flange 46, and aspirally-formed transparent tube 44 is disposed in the housing 42 andfilled with a suitable inert gas which will emit a red glow, whensuitably energized by electricity. An intermediate lamp housing 48 isdisposed in another of said openings and secured thereto by the flange52 and a helical transparent tube is disposed in the housing 48, whichtube is filled with an inert gas which will emit a yellow or amber glowwhen energized by a source of electrical potential. The lower opening54, in the side walls 26 and 30 is provided for the reception of thetransparent tube, shaped as is best shown in Figure l to provide innerand outer concentric coils 56 and 58, which coils are filled with aninert gas which will emit a green glow, when energized. The relativelyparallel side walls 28 and 32, which side walls are disposedtransversely of the side walls 26 and 36 are also provided with aplurality of vertically spaced openings an upper lamp housing 60 beingmounted in one of the openings, as by the flange 62 with a suitable redlamp 64 disposed in the housing, and an intermediate housing 66, asmounted in the side walls 28 and 32 below the upper housing, by theflange 88, and an amber lamp I0 is disposed in the intermediate housing.The lower opening 69 in the side walls 28 and 32 has a green lamp I2formed in the same manner as the corresponding lamp on the side walls 26and 30. It may be noted, at this time, that the lamps and lamp housingon the side walls 26 and 30 are spaced vertically above thecorresponding lamps and lamp housing on the side walls 28 and 32, forreasons which will later become apparent as the following descriptionproceeds. Additionally, it will be appreciated that it is not imperativethat there be provided four similar lamp units, one on each of the sidewalls, it merely being necessary, for the purposes of this invention, toprovide a pair of lamp units, each disposed on relatively transverseside walls such as 28 and 30.

A rectangular inner casing I4 including side panels I6 is disposedwithin the housing I2, with one of the side panels paralleling each ofthe side walls of the housing which casing is secured to the bottom 20of the housing, as by corner posts I8, and the top panel 80 which issecured to the corner posts, by fasteners 82, and which overlies theupper ends of the side panels of the casing. Bushings 84 are carried byeach of the side panels I6, in registry with each of the openings 54 and69 in the side walls of the housing, and an indicator support shaft 86is rotatably journaled in each of the bushings.

An indicator light assembly I4 is mounted on the end of each of theshafts 86 and includes a 4 dish-shaped housing 88 which is secured tothe shaft as by the nut 90, and which housing has an inwardly directedflange 92 adjacent to the open end thereof by means of which the opaquefront panel 94 is secured to the housing. An indicator lamp 06 ismounted in the socket 98 carried by the indicator light housing 88, inregistry with an opening I00 in the front panel 84, which opening islaterally offset from the axis of rotation of the housing 88. It iscontemplated that the housing 88 be either formed of an electricallyinsulative material, so that the slip rings I02 and I04 which aresecured, by fasteners I06 and I08 respectively to the back of thehousing, will be electrically insulated from each other, and from theremainder of the traflic signal light. Alternatively, 'if the housing 88is not formed of insulative material, the slip rings may be insulatedtherefrom, in any conventional manner. As is best shown in Figure 2, theslip rings I02 and I04 are each electrically connected to the lampsocket 08, by conductors I I0, and suitable brushes I I2 and I I 4, aresecured to one of the side panels I6 of the casing I4, each of thebrushes respectively contacting the slip rings I02 and H14.

It will thus be appreciated that as the housing 88 rotates about theshaft 86 that the lamp 96 may be illuminated through the intermediary ofthe brush and slip ring assembly, described above. As each of theindicator light assemblies I4 are the same, a description of one of theassemblies is deemed sufficient.

A motor (not shown) is disposed within the lower portion of the casingI4 and has a drive shaft H6 which extends through the bushing H8 in thepartition I20, a first and a second set of bevelled drive gears I20 andI22 being nonrotatably secured to the shaft H6, in longitudinally spacedrelation to each other. A first set of bevelled gears I24 are disposedin meshing engagement with the drive gear I20, which driven gears arerotatably supported for movement about a horizontal axis, on thejournals I26 carried by the partition I20. A clutch member I23 issecured in the stub shaft (not shown) which supports the bevelled gearsI24, and is movable with the latter, and a relatively movable matingclutch member I30 is disposed in sliding, but relatively non-rotatableengagement with the indicator assembly support shafts 86. Thus, when theclutch member I30 is moved axially of the shaft 86, into and out ofengagement with the clutch member I28, the indicator support shaft 86,and the housing 88 carried thereby is drivingly connected to the driveshaft II6.

A plurality of vertically disposed standards I32 are secured to thepartition I20, in any desired manner, and extend upwardly therefrom, ahorizontally disposed rod I34 being secured between adjacent standardsas is best shown in Figures 2 and 4. A clutch actuating yoke I36 has oneend thereof vertically pivotally attached, as at I38 to the rod I34, andretained in position by collars I40. The yoke I36 has a pair of inwardlydirected fingers I 42 which engage in the recess I44 in the matingclutch member I30, whereby "the clutch actuating yoke is operativelyconnected to the movable clutch member I30. The other of the drive gearsI22 is in meshing engagement with a driven bevelled gear I46 carried bya stub shaft (not shown), which stub shaft is rotatably supported on thejournal I48 (see Figure 3). Mating clutch members I50 and I52 arerespectively carried by the stub shaft nponnwhichzthe; drirenrsear .:I2416 :is; secured; and

cams..zs4,..25e,.2.53am:26c are nonr-rotatably attached to the camshaft,and suitably spaced thereonbyspacers 2.62. Springs 264 are attached toone end of. eachof the contact .armsandto the bracket 212, to yieldinglyurge the contact arms-22d, 222,224 and. 226 respectively into, en-

gagement withthe contact terminals 238 ,2410,

244 and 246. The block 228 on each of the arms rides against itsrespective cam whereby the contact arms are each cyclically pivotedabout the pin 2M, in opposition to the spring 264, into contact with theopposed contact terminals, as will be best appreciated from aconsideration of Figure '7.

The arm 220 is connected by conductor 266 to a source of power, thecontact terminal 236 being connected by conductors 268 to the red lamps44, while the contact terminal 238 is connected by conductors 210 to thered lamp 64. The contact arm 222 is also connected by a conductor 212 toa source of power, while the contact terminal 240 engaged thereby isconnected by conductors 214 to the caution or amber lamps 50 and 10, thecam 256 being suitably designed to close the contact between the arm andthe terminal 240, twice each revolution of the shaft 252. The arm 224 isalso connected by a conductor 216 to a source of power while the contactterminal 242 is connected by conductors 218 to the green lamps 12, thecontact terminal 244 being connected byconductors 280 to the green lamps58. The solenoid actuating control arm 226 is also connected to thesource of power, as by conductor 282, and the contact terminal 246engaged thereby is connected by the conductor 284 to the solenoid I92,so as to energize the latter upon closing of contact between the arm 226and terminal 246.

In operation, assuming that the motor drives the driven shaft H6,through suitable reduction gearing, one revolution per minute, and thegear I24 is driven by the shaft H6, and completes a revolution in thirtyseconds, the gear I46, also driven by the shaft H6, completing onerevolution in twenty seconds. The gears 248 and 256 are then soconstructed that the cam shaft 252 will complete one revolution in fiftyseconds, or the composite time necessary for both the gears I24 and M6to complete one revolution.

Cam 260 is so dimensioned that the lobe thereof will retain the arm 226out of engagement with the terminal 2 36 for three-fifths of therevolution of the cam shaft. While the arm 226 is out of engagement withthe terminal 246, the cam 258 moves the arm 224 into contact with theterminal 242, to energize the green lamps I2, and the indicating lights96 carried thereby, whereby those indicating lamps which are beingrotated by the drive shaft I IE will be simultaneously energized.

Obviously, when the green light 12 is actuated, the cam 255 moves thearm 220 into contact with the terminal 236, to energize the red lamps 44on the relatively transverse set of lamps, it being understood that thecam 256 will actuate the caution lights 56 and 16, a predetermined timeinterval, such as three seconds, prior to the deactuation of therespective green lamps, and indicating lamps 96.

As a single motor is utilized tocontrol rotation of the indicatinglamps, and to also control the connecting and disconnecting of theindicating lamps from the motor, while additionally controlling theenergization of all of the lamps, it is to be noted that variations inspeed of the motor will not affect the relative timing in the trafiiclight. Additionally, since one of the indicating lamps is operativelydisconnected from the drive shaft H6, when the relatively transverseindicating lamp is guidingly connected thereto, it will be appreciatedthat the gearing utilized to drive the respective indicating lamps maybe so constructed that the relatively trans- E5 versely disposedindicating lamps at different rates of speeds.

As it is thought that the operation and construction of the device maybe readily understood from the foregoing, further description isbelieved to be unnecessary. However, since numerous modifications willreadily occur to those skilled in the art after a consideration of theforegoing specification and accompanying drawings, it is not intended tolimit the invention to that shown and described, but all suitablemodifications may be resorted to falling within the scope of theappended claims.
